You mention Roku Stick, but have Roku Premiere pictured, which isn't considered a stick. If you have two premieres, the remotes it comes with are IR only, and don't control TV's. You can purchase separately two Wifi remotes and pair it with premieres and the remote will only control a single roku at a time. If the TV's use the same code set, this won't fix that sorry. If you really had Roku stick, the only remote to control them are Wifi remotes and so wouldn't have controlled two roku at the same time. Even if you wanted too.
